Navigating Ancient Asteroid Strike A Guide for Cultural Historians

As cultural historians, we are often drawn to the mysteries of the past. The recent discovery of an ancient asteroid strike on the moon, which carved out two grand canyons on the lunar far side, is a prime example of this fascination. In this article, we will delve into the findings and provide guidance for navigating this remarkable event.

The Impact A Geological Marvel

The asteroid, estimated to be approximately 15 miles in diameter, slammed into the moon around 3.8 billion years ago. This violent collision created a massive basin and sent streams of boulders hurtling at speeds of nearly 1 mile per second (1 kilometer per second). In just 10 minutes, this geologic process formed two canyons comparable in size to Arizona's Grand Canyon.

Calculating the Debris Path A NASA-Led Effort

Scientists used data and photos from NASA's Lunar Reconnaissance Orbiter to map the area and calculate the path of debris. According to lead author David Kring, the asteroid passed over the lunar south pole before hitting, creating a huge basin and sending debris hurtling at incredible speeds. The debris landed like missiles, digging out the two canyons.

The Power of Ancient Asteroid Impacts

To put this into perspective, the energy released by the asteroid strike would have been more than 130 times that in the world's current inventory of nuclear weapons. This demonstrates the immense power of ancient asteroid impacts and their potential to shape the lunar surface.

Implications for Future Exploration A New Frontier

The discovery of these canyons has significant implications for future moon exploration. The debris field created by the asteroid strike means that NASA's targeted exploration zone around the pole on the near side will not be buried under debris, keeping older rocks from 4 billion years ago exposed for collection by moonwalkers.

Shadowed Areas A Potential Resource

One area of interest is whether these canyons are permanently shadowed like some of the craters at the moon's south pole. Kring notes that it is unclear if the two canyons are permanently shadowed, stating, That is something that we're clearly going to be reexamining. Permanently shadowed areas at the bottom of the moon are thought to hold considerable ice, which could be turned into rocket fuel and drinking water by future moonwalkers.

The Artemis Program A New Era in Space Exploration

The discovery of these canyons comes as NASA prepares to return astronauts to the moon through its Artemis program. The plan is to send astronauts around the moon next year, followed by the first lunar touchdown by astronauts since Apollo in 2025. This new information will likely inform NASA's plans and enhance our understanding of the moon's geologic history.

Conclusion A New Frontier for Cultural Historians

The ancient asteroid strike that carved out two grand canyons on the moon is a remarkable event that has significant implications for cultural historians and space exploration enthusiasts alike. By understanding the impact, calculating the debris path, and exploring the power of ancient asteroid strikes, we can gain new insights into the moon's geologic history and its potential for future human exploration.
